Description

Technical Field

[0001] The present invention relates to the field of furniture, in particular to an invisible connector. Background Art

[0002] As users demand increasingly higher aesthetics and quality in furniture, more and more users are opting for custom wooden furniture. However, since wooden furniture is typically constructed from multiple planks, existing wood assembly methods are cumbersome and require external tools for locking, making installation and disassembly difficult. This is especially true when customizing wooden furniture, where the difficulty of the assembly process varies greatly. Using connectors, existing connectors cannot be completely concealed, resulting in poor aesthetics. While using mortise and tenon joints effectively solves the problem of exposed connectors on the furniture surface, their splicing requires high machining precision, and the complex assembly process for the connecting components makes them unsuitable for mechanized production. Summary of the Invention

[0026] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0027] Please refer to Figures 1-8 , an invisible connector, comprising a female component embedded in a first component to be spliced ​​and two male components;

[0028] The female component includes a connector and a shell with an installation cavity inside, and the connector is installed on one side of the shell;

[0029] The other side of the housing is provided with two limiting holes and two arc-shaped sliding grooves communicating with the mounting cavity, wherein the two limiting holes are symmetrically arranged and the two sliding grooves are symmetrically arranged;

[0030] The first end of the chute is open, and the second end of the chute is connected to the limiting hole;

[0031] The limiting body of the male component can be inserted into the first end of the sliding groove and the main body of the male component can be embedded in the limiting hole, and the main body of the male component is used to be embedded in the second component to be spliced;

[0032] When the limiting body is located in the installation cavity and the main body is embedded in the limiting hole, the male component is limited in the X-axis direction and the Z-axis direction at the same time.

[0033] The working principle of the present invention is:

[0034] The female component is embedded in the first component to be connected, and the main body of the male component is embedded in the second component to be connected, so that the limiting body of the male component is inserted into the installation cavity of the female component through the slide groove, and the male component is limited by the limiting hole, which simplifies the overall structure of the connector and simplifies the assembly process.

[0035] As can be seen from the above description, the beneficial effects of the present invention are as follows: the present invention sets a male part and a female part, which can quickly and conveniently connect two parts to be spliced ​​and is easy to disassemble. Two sliding grooves and two limiting holes are opened on one side of the shell of the female part, and one end of the male part is connected to the second part to be spliced. The other end limits the other end of the male part through the sliding groove and the limiting hole in turn, and can simultaneously connect two second parts to be spliced ​​with one first part to be spliced, which simplifies the connection method and makes assembly simpler. The male part can be connected to the female part in a sliding manner, which is easy to assemble and disassemble, and the female part can be completely embedded in the first part to be spliced. The limiting body of the male part can be embedded in the female part, achieving the effect of completely hiding the connecting part, making the furniture more beautiful as a whole. The present invention has a simple structure, is easy to install and disassemble, and can also be completely invisible in the furniture, improving the aesthetics.

[0036] Furthermore, the diameter of the limiting body is larger than the diameter of the main body; the diameter of the limiting body is larger than the diameter of the limiting hole.

[0037] From the above description, it can be seen that the diameter of the limiting body is larger than the diameter of the limiting hole. After the main body is embedded in the limiting hole, the limiting body is also limited in the Z-axis direction to ensure the connection stability between the male part and the female part.

[0038] Furthermore, the caliber of the first end is larger than the caliber of the second end, and the caliber of the first end is larger than the diameter of the limiting body.

[0039] From the above description, it can be seen that the caliber of the first end is larger than the caliber of the second end and the caliber of the first end is larger than the diameter of the limiter, ensuring that the limiter can be inserted into the installation cavity through the slide groove, and when the main body is embedded in the limiter hole, the limiter can be limited.

[0040] Furthermore, the outer surface of the connector is provided with multiple rows of anti-slip teeth;

[0041] The outer sides of the anti-slip teeth are gradually inclined outwardly in a direction from the connector to the housing;

[0042] The side of the anti-slip teeth facing the housing is perpendicular to the connecting body.

[0043] As can be seen from the above description, the provision of anti-slip teeth increases the friction between the connector and the first component to be connected, thereby improving the stability of the connection between the mother component and the first component to be connected.

[0044] Furthermore, a U-shaped groove is provided on a side of the shell away from the connector, and the sliding groove and the limiting hole are provided on one side of the U-shaped groove.

[0045] Furthermore, an annular limiting platform matching the U-shaped groove is provided at one end of the main body close to the limiting body. When the limiting body is embedded in the shell, the limiting platform can be pressed against one side of the U-shaped groove.

[0046] It can be seen from the above description that by providing a ring-shaped limiting platform that matches the U-shaped groove, the limiting platform can further limit the position of the male component in the Z-axis direction.

[0047] Furthermore, the outer surface of the main body is provided with external threads.

[0048] As can be seen from the above description, the provision of external threads enables the main body to be installed into the second piece to be assembled in a rotational manner, which makes assembly simple and more secure.

[0049] Furthermore, both sides of the slide groove are arc-shaped and the diameter gradually decreases from the first end to the second end.

[0050] Furthermore, the arcs on both sides of the slide groove are bent toward the same side.

[0051] From the above description, it can be seen that a slide groove is set. Since the limit platform matches the U-shaped groove, and the arcs on both sides of the slide groove are bent toward the same side, if the male part wants to slide out of the groove, the limit platform will limit the movement of the male part. At this time, it is necessary to rotate one side of the limit platform to disengage from the U-shaped groove and press against one side of the shell so that the male part can be separated from the shell.

[0052] The invisible connector of the present invention is suitable for connecting various types of plates.

[0053] Example 1

[0054] Reference Figure 1 , an invisible connector, comprising a female component 3 and two male components 4 embedded in a first component to be spliced ​​1; the female component 3 comprises a connector 31 and a shell 32 with an internal mounting cavity 323, the connector 31 being mounted on one side of the shell 32; the other side of the shell 32 is provided with two limiting holes 321 and two arc-shaped slide grooves 322 communicating with the mounting cavity 323, the two limiting holes 321 being symmetrically arranged, and the two slide grooves 322 being symmetrically arranged; the first of the slide grooves 322 The end 3221 is open, and the second end 3222 of the slide groove 322 is connected to the limiting hole 321; the limiting body 41 of the male component 4 can be inserted into the first end 3221 of the slide groove 322 and the main body 42 of the male component 4 can be embedded in the limiting hole 321, and the main body 42 end of the male component 4 is used to connect with the second to-be-assembled component 2; when the limiting body 41 is located in the installation cavity 323 and the main body 42 is embedded in the limiting hole 321, the male component 4 is limited in the X-axis direction and the Z-axis direction at the same time.

[0055] Example 2

[0056] In this embodiment, the first piece to be assembled 1 and the second piece to be assembled 2 are both wooden boards.

[0057] The differences between this embodiment and the first embodiment are as follows:

[0058] Reference Figure 1 , the diameter of the limiting body 41 is larger than the diameter of the main body 42 ; the diameter of the limiting body 41 is larger than the caliber of the second end 3222 .
